What Postgres version?

In version 12 and 14 I get:

select initcap('notemachine');
    initcap
-------------
  Notemachine

select initcap('Sainsbury''s Bank');
      initcap
------------------
  Sainsbury'S Bank


Which follows the definition here:

https://www.postgresql.org/docs/14/functions-string.html

initcap ( text ) → text

Converts the first letter of each word to upper case and the rest to
lower case. Words are sequences of alphanumeric characters separated by
non-alphanumeric characters.
